Problems solved by technology

However, the white ink layer and the color ink layer have a strong shielding effect on solar light. The shaded photovoltaic chip will be used as a load to consume the energy generated by other illuminated solar cell components, and the shaded photovoltaic chip will heat up at this time. , forming a hot spot effect, which seriously reduces the energy efficiency of photovoltaic wafers
Moreover, the titanium dioxide particles in the white ink layer also reflect the light irradiated on the solar photovoltaic module, reducing the energy efficiency of the solar photovoltaic module

Abstract

The invention provides a color photovoltaic module with improved efficiency, which sequentially comprises a pattern part for bearing colors and a solar photovoltaic module from top to bottom, and is characterized in that the pattern part comprises a white ink layer formed by printing and a color ink layer formed by printing. By adjusting the color gradation of a picture with a required pattern, printing software controls the ink output of white ink when a printer prints the white ink layer by identifying different color gradations in the picture, and meanwhile, controls a black place and a white place not to output ink when the printer prints the color ink layer. Through the method, the usage amount of the white ink is reduced, the production cost of the color photovoltaic module is reduced, the shielding effect of the photovoltaic module can be effectively reduced, the reflection of the white ink layer to sunlight is reduced, the efficiency of the photovoltaic module and the safety ofthe photovoltaic module are effectively improved, the black color of the photovoltaic wafer can be fully utilized, and the production cost of the color photovoltaic module is reduced. The stereoscopic impression of the pattern is effectively improved, and the color gradation of the pattern is more obvious and richer.

Description

technical field [0001] The invention belongs to the technical field of photovoltaic modules, and in particular relates to a color photovoltaic module with improved efficiency and a preparation method thereof. Background technique [0002] As the concept of building photovoltaic integration has been more and more widely recognized in the field of photovoltaics, people hope to choose their favorite colors to decorate their buildings and highlight the personality of buildings for photovoltaic products as building materials, which requires Photovoltaic modules come in a variety of colors to suit aesthetic requirements. There are generally two ways to form the existing color photovoltaic modules. One is to directly print a white ink layer on a screen printing machine or a UV printing machine and then print a color ink layer on the white ink layer to form a color photovoltaic module; A color ink layer is printed on the glass plate, and then a white ink layer is printed on the col...
